Tesla Holiday Update: New UI for Model 3 and Y, Light Show, blind spot camera improvements & more
Just a few days before Christmas, Tesla is kicking off the holidays with a bang. This year’s Holiday Update includes a few fun surprises for Tesla owners, including new games and a few other fun features.
Teslascope, a Tesla software update tracker service, has shared that the 2021.44.25 update is being rolled out to employees for now, with a wide release following in the lead up to Christmas. Reports shared online suggest that the update works very smoothly on vehicles like the Model 3 and Model Y, however.
New Features
First off is the Light Show, which enables Tesla vehicles to dance to a choreographed light show any time of the year. The feature was a signature trick of the Model X, so it is pretty interesting that Tesla is now rolling it out to the other vehicles in its lineup. The Light Show feature can be accessed through the Toybox.
In its Holiday Update, Tesla also introduced the Customizable App Launcher, allowing owners to customize the menu bar in their infotainment systems. This should go perfectly hand-in-hand with the Model 3 and Model Y’s update UI, which now matches the interface of the Model S Plaid and new Model X that were rolled out this year.
“Drag and drop your favorite apps to any position along the bottom menu bar for easy access. To customize your menu bar, hold any icon and then drag to reorder. To adjust climate controls such as heated seats and defrost, tap on the temperature or swipe up from the bottom of the screen,” the update’s Release Notes read.
Feature Improvements
As with any update, Tesla improved a few key features, including vehicle controls, blind spot monitoring, and Waypoints.
Simplified Controls makes it easier for Tesla owners to focus on navigation, media, and the most common primary controls. The improvement should make accessing features in the infotainment system easier, so driving or operating a Tesla may be more convenient and perhaps even safer.
The Blind Spot Camera feature is probably one of the best improvements in the Tesla Holiday update, as it provides vehicles with a video feed showing their blind spot when a turn signal is activated. “You can now automatically see a live camera view of your blind spot whenever you activate the turn signal,” the Release Notes for the feature read.
The Blind Spot Camera feature will most likely improve the safety of Tesla’s vehicles. Tap Controls>Autopilot>Automatic Blind Spot Camera to enable the feature.
Tesla also made trips easier with Edit Waypoints. The navigation improvements will probably be quite useful to families taking trips this holiday. The feature allows drivers to reorder or add multiple destinations to their route. Edit Waypoints will update the arrival times for each change on the route. “To add a stop, or edit a trip, initiate a navigation route, and tap the more options button not he turn list,” wrote Tesla on the Edit Waypoints Release Notes.
New Arcade Improvements
Being a Holiday Update, 2021.44.25 is rife with a number of improvements for Tesla Theater and Tesla Arcade. Access to a popular social media platform has also been enabled.
First up is Sonic the Hedgehog, which Elon Musk himself announced on Twitter recently. Multiplayer support for The Battle for Polytopia has also been enabled, which should make in-car gaming sessions even more fun.
Sudoku has also been added to the Tesla Arcade, complete with a mode that includes a smart hint system for beginners. Also, the popular social media app TikTok is now accessible to Teslas.
Other Improvements
Update 2021.44.25 is not all fun and games. Tesla included some Cold Weather Improvements to its Holiday Update, too. Preconditioning the cabin from the Tesla Mobile App when the battery is at a lower state of charge is now enabled. First row seat heaters can now automatically regulate seat temperatures based on the cabin’s environment and control set temperature.
Managing dashcam clips is also easier, as videos can now be deleted directly from the infotainment system. Themes for the infotainment system have been rolled out, too. For instance, Dark Mode is now available for Tesla displays. Dark Mode may be a simple update, but it could make vehicles safer, as a darker display reduced the chance of screen glare for the driver.

Tesla Full Self-Driving’s newest behavior is the perfect answer to aggressive cars
According to a recent video, it now appears the suite will automatically pull over if there is a tailgater on your bumper, the most ideal solution for when a driver is riding your bumper.
Tesla Full Self-Driving appears to have a new behavior that is the perfect answer to aggressive drivers.
According to a recent video, it now appears the suite will automatically pull over if there is a tailgater on your bumper, the most ideal solution for when a driver is riding your bumper.
With FSD’s constantly-changing Speed Profiles, it seems as if this solution could help eliminate the need to tinker with driving modes from the person in the driver’s seat. This tends to be one of my biggest complaints from FSD at times.
A video posted on X shows a Tesla on Full Self-Driving pulling over to the shoulder on windy, wet roads after another car seemed to be following it quite aggressively. The car looks to have automatically sensed that the vehicle behind it was in a bit of a hurry, so FSD determined that pulling over and letting it by was the best idea:
Tesla appears to be implementing some sort of feature that will now pull over if someone is tailgating you to let the car by
Really cool feature, definitely get a lot of this from those who think they drive race cars

We can see from the clip that there was no human intervention to pull over to the side, as the driver’s hands are stationary and never interfere with the turn signal stalk.
This can be used to override some of the decisions FSD makes, and is a great way to get things back on track if the semi-autonomous functionality tries to do something that is either unneeded or not included in the routing on the in-car Nav.
FSD tends to move over for faster traffic on the interstate when there are multiple lanes. On two-lane highways, it will pass slower cars using the left lane. When faster traffic is behind a Tesla on FSD, the vehicle will move back over to the right lane, the correct behavior in a scenario like this.
Perhaps one of my biggest complaints at times with Full Self-Driving, especially from version to version, is how much tinkering Tesla does with Speed Profiles. One minute, they’re suitable for driving on local roads, the next, they’re either too fast or too slow.
When they are too slow, most of us just shift up into a faster setting, but at times, even that’s not enough, see below:
What has happened to Mad Max?
At one point it was going 32 in a 35. Traffic ahead had pulled away considerably https://t.co/bjKvaMVTNX pic.twitter.com/aaZSWmLu5v

There are times when it feels like it would be suitable for the car to just pull over and let the vehicle that is traveling behind pass. This, at least up until this point, it appears, was something that required human intervention.
Now, it looks like Tesla is trying to get FSD to a point where it just knows that it should probably get out of the way.

Tesla Megapack powers $1.1B AI data center project in Brazil
By integrating Tesla’s Megapack systems, the facility will function not only as a major power consumer but also as a grid-supporting asset.
Tesla’s Megapack battery systems will be deployed as part of a 400MW AI data center campus in Uberlândia, Brazil. The initiative is described as one of Latin America’s largest AI infrastructure projects.
The project is being led by RT-One, which confirmed that the facility will integrate Tesla Megapack battery energy storage systems (BESS) as part of a broader industrial alliance that includes Hitachi Energy, Siemens, ABB, HIMOINSA, and Schneider Electric. The project is backed by more than R$6 billion (approximately $1.1 billion) in private capital.
According to RT-One, the data center is designed to operate on 100% renewable energy while also reinforcing regional grid stability.
“Brazil generates abundant energy, particularly from renewable sources such as solar and wind. However, high renewable penetration can create grid stability challenges,” RT-One President Fernando Palamone noted in a post on LinkedIn. “Managing this imbalance is one of the country’s growing infrastructure priorities.”
By integrating Tesla’s Megapack systems, the facility will function not only as a major power consumer but also as a grid-supporting asset.
“The facility will be capable of absorbing excess electricity when supply is high and providing stabilization services when the grid requires additional support. This approach enhances resilience, improves reliability, and contributes to a more efficient use of renewable generation,” Palamone added.
The model mirrors approaches used in energy-intensive regions such as California and Texas, where large battery systems help manage fluctuations tied to renewable energy generation.
The RT-One President recently visited Tesla’s Megafactory in Lathrop, California, where Megapacks are produced, as part of establishing the partnership. He thanked the Tesla team, including Marcel Dall Pai, Nicholas Reale, and Sean Jones, for supporting the collaboration in his LinkedIn post.

Starlink powers Europe’s first satellite-to-phone service with O2 partnership
The service initially supports text messaging along with apps such as WhatsApp, Facebook Messenger, Google Maps and weather tools.
Starlink is now powering Europe’s first commercial satellite-to-smartphone service, as Virgin Media O2 launches a space-based mobile data offering across the UK.
The new O2 Satellite service uses Starlink’s low-Earth orbit network to connect regular smartphones in areas without terrestrial coverage, expanding O2’s reach from 89% to 95% of Britain’s landmass.
Under the rollout, compatible Samsung devices automatically connect to Starlink satellites when users move beyond traditional mobile coverage, according to Reuters.
The service initially supports text messaging along with apps such as WhatsApp, Facebook Messenger, Google Maps and weather tools. O2 is pricing the add-on at £3 per month.
By leveraging Starlink’s satellite infrastructure, O2 can deliver connectivity in remote and rural regions without building additional ground towers. The move represents another step in Starlink’s push beyond fixed broadband and into direct-to-device mobile services.
Virgin Media O2 chief executive Lutz Schuler shared his thoughts about the Starlink partnership. “By launching O2 Satellite, we’ve become the first operator in Europe to launch a space-based mobile data service that, overnight, has brought new mobile coverage to an area around two-thirds the size of Wales for the first time,” he said.
Satellite-based mobile connectivity is gaining traction globally. In the U.S., T-Mobile has launched a similar satellite-to-cell offering. Meanwhile, Vodafone has conducted satellite video call tests through its partnership with AST SpaceMobile last year.
For Starlink, the O2 agreement highlights how its network is increasingly being integrated into national telecom systems, enabling standard smartphones to connect directly to satellites without specialized hardware.
